Definition & Meaning
Kilonovae are astronomical events that occur when two neutron stars or a neutron star and a black hole merge. These phenomena result in a colossal explosion, ejecting heavy elements into space and producing gravitational waves and a short gamma-ray burst. Studying kilonovae is crucial for understanding the formation of elements heavier than iron and the dynamics of neutron star mergers.
